-/**
- * This class represents the special screen elements to control a window on free form
- * environment. All thse screen elements are added in the "non client area" which is the area of
- * the window which is handled by the OS and not the application.
- * As such this class handles the following things:
- * <ul>
- * <li>The caption, containing the system buttons like maximize, close and such as well as
- * allowing the user to drag the window around.</li>
- * <li>The shadow - which is changing dependent on the window focus.</li>
- * <li>The border around the client area (if there is one).</li>
- * <li>The resize handles which allow to resize the window.</li>
- * </ul>
- * After creating the view, the function
- * {@link #setPhoneWindow} needs to be called to make
- * the connection to it's owning PhoneWindow.
- * Note: At this time the application can change various attributes of the DecorView which
- * will break things (in settle/unexpected ways):
- * <ul>
- * <li>setElevation</li>
- * <li>setOutlineProvider</li>
- * <li>setSurfaceFormat</li>
- * <li>..</li>
- * </ul>
- * This will be mitigated once b/22527834 will be addressed.
